Math Replacement Update April 15, 2016 Topics Covered Topics Covered Students use Multiplication/Division Diagrams to help organize information in number stories and write number models for the problems. Students review the role of ONE, and to explore mixed-number concepts. They name, and convert between, mixed numbers and improper fractions. Students explore the multiples-of-10 strategy as one of many ways to solve equal-grouping division number stories Students use multiple strategies to show equivalent fractions, compare pairs of fractions, and continue their exploration of fraction addition. Students learn and practice a paperand-pencil algorithm for division that permits them to build up the quotient by working with easy numbers. Coming Up Final full week of PARCC testing Solve division number stories and interpret remainders Use arrays to model division Form angles of a given measure Investigate the relationship between rotations and degrees. Students review how to plot ordered number pairs on a rectangular coordinate grid. They plot and name vertices of polygons. Students also explore the relationship between the coordinates of the endpoints and midpoints of line segments. Students review geometry vocabulary terminology with an emphasis on angles, polygon shapes, and the coordinate grid. Students explore and apply the special relationships between angles that are formed when parallel lines are cut by a transversal. Students review addition and subtraction of fractions with like and unlike denominators. Coming Up - - - - Week of April 18 - - - - - - - Week of April 25 - - - Coming Up - - - - Week of April 18 - - - Students change fractions to equivalent fractions having denominators of 10 or 100 and then rename these fractions as decimals. Topics Covered Final full week of PARCC testing Organize data using a picture, graph, line plot, table, and list Identify data landmarks for data sets - - - - Week of April 18 - - - - - - - Week of April 25 - - - Use clock models and pencil-andpaper algorithms to add and subtract fractions Use common denominators to add and subtract fraction pairs Final full week of PARCC testing Identify the absolute value of rational numbers Define and find reciprocal of a number - - - - Week of April 25 - - - Review addition, subtraction, multiplication, and division of both positive and negative numbers Write a special case to illustrate a general pattern SCHOLASTIC DYNAMATH / MATH MAGAZINE are DUE Monday, May 2nd ! ! ! ! ! ! ! ! ! !
